CDM Fibran XPS-500C - 50mm-deep thermal insulation board

Newton CDM Fibran XPS-500C, produced exclusively for Newton Waterproofing, is a 50mm-deep, closed-cell thermal insulation board made from rigid extruded polystyrene foam (XPS).

The insulation boards are used to form a 50mm spacer adjacent to the CDM BaseDrain and CDM FloorDrain drainage channels within the Newton CDM System cavity drain waterproofing system. Rated at 500 kPa, the boards feature specifically-designed slots to the underside that, in combination with the perimeter and spine drainage channels of the Newton CDM System, form a fully-drained supporting spacer below the floor drainage membrane.

CDM Fibran XPS-500C boards can also be used as a protection for Newton liquid-applied waterproofing membranes applied externally to new earth-retained structures or retained walls, offering protection, insulation and drainage within one product.

Key benefits

• Excellent thermal insulation characteristics with a very low coefficient of thermal conductivity

• Closed cell structure with no connecting capillaries resulting in extremely high resistance to water absorption and diffusion of water vapour

• Capable of permanent submersion in water

• Fully inert when subjected to climatic variations

• High mechanical and compressive strength and high dimensional stability

• Contains no CFC or HCFCs

• Life expectancy is equivalent to the building in which it is installed (estimated 50 years)

• 100% recyclable

• Easy to transport, cut and apply

• Completely rot proof and does not develop any mould or other efflorescence

• No nutritional value for rodents, insects, etc

• Good resistance to acids, alkalines, aggressive ground containments and inorganic gases

Typical applications

• As the spacer below Newton cavity drain waterproofing floor membranes

• Protection of Newton liquid applied waterproofing membranes applied externally to retained walls

• Insulated support below HydroBond 403 Plus

• Parking decks and green roofs

• Full external envelope insulating of subterranean structures sited permanently within the water table

Suitable substrates

• Compacted, clean and level surfaces

• Basement concrete floor slabs and rafts

• Earth-retained walls of concrete, mortar or ICF

• Compacted blinding
